Hi,
I would like to use QHD resolution (2560x1440) with my shiny new computer and display. That resolution works if I boot Windows 10 (cough).
What do I need to do to use that resolution in Linux?
I first tried openSUSE 15.3 (kernel 5.3.18-59.19-default) then I build a v5.14 kernel and tried that. Both of them max out at FHD (1920x1080).
I am booting with "i915.force_probe=4c8a" on the kernel command line.
My desktop is XFCE4.
CPU is: processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 167 model name : 11th Gen Intel(R) Core(TM) i9-11900 @ 2.50GHz stepping : 1 microcode : 0x40 cpu MHz : 1021.742 cache size : 16384 KB physical id : 0 siblings : 16

Dunno if I can 'help' get everything going - - - - but I do have some ideas (having had to fight a lot to get my graphics sub-system working).
Start up a terminal as your user and run $ xrandr --verbose and then if you would paste the lines up to the end of the EDID blob here. (Need more info that what you provided. )

I first tried openSUSE 15.3 (kernel 5.3.18-59.19-default) then I build a v5.14 kernel and tried that. Both of them max out at FHD (1920x1080).
I am booting with "i915.force_probe=4c8a" on the kernel command line.
I'm guessing you're hitting some dual mode adapter limit.
Please file a bug over at [1], add drm.debug=14 module parameter, and attach dmesg from boot to hitting the issue.
BR, Jani.
